It's supposed to change colors but it doesn't . I also tried Toasty Puff on bud because I saw it in High Times. Mr Bubble flavor tastes alright while inhaling but has a much better aftertaste. The smell it gives off was like burnt bubblegum. Too much dripped on your bowl is cause for a harsher hit.
Thats what color changing pipes do, the more you smoke the more they change. Grats on the bowl, looks pretty.
Yeah, color changingn really means that fumed in colors (silver makes it blue, gold makes it golden-red) start to show up more clearly as dark resin builds up inside. To really see a glass piece like that show all its colors it needs to be thoroughly gunked-up... one reason not to keep your pipe clean.
i have a pipe with glass just like that but i have a huge sherlock. mine changed a nice white then to a sick metalic blue at the moment. just keep toking it and youll see
